Is port 1995 dangerous?

We have no specific security note for port 1995. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 1995, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1995'      # process listening on 1995
sudo lsof -nP -i :1995

macOS

sudo lsof -nP -i :1995

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1995 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1995
netstat -ano | findstr :1995

From another machine

nmap -p 1995 -sV <host>
sudo nmap -sU -p 1995 <host>
nc -zv <host> 1995

Block it in the firewall

sudo ufw deny 1995/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1995" -Direction Inbound -LocalPort 1995 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1995 used for?

Port 1995 is assigned by IANA to perf-port (cisco perf port).

Is port 1995 TCP or UDP?

Port 1995 is registered for TCP and UDP.

Is it safe to open port 1995?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 1995 is open?

On Linux run "ss -ltnup 'sport = :1995'", on macOS "lsof -nP -i :1995", and on Windows "netstat -ano | findstr :1995" to see the local process. From another machine, "nmap -p 1995 <host>" shows whether it is reachable.
